Ceylon Spiny Mouse

The Ceylon Spiny Mouse (Mus fernandoni) is a species in the genus Mus. It is currently classified as Endangered on the IUCN Red List.

Common Potoo

A nocturnal bird of tropical forests across Central and South America from Mexico to Argentina, common potoos are masters of cryptic camouflage, roosting motionless on broken tree stumps or branches during the day with eyes barely open, resembling bark so perfectly they are nearly invisible to predators. At night they hunt large insects from exposed perches with their enormous gape. Their mournful, wailing calls — often described as haunting or eerie — carry through tropical forest nights.
